【摘要】：目的:研究不同体重人群在平均耗氧量相同情况下两种不同运动方法底物代谢和能量消耗特征。方法:采用实验法获取肥胖组和正常体重组在持续运动和间歇运动过程中的底物代谢和能量消耗特征。受试者进行三项运动测试:(1)以50%VO2max的运动强度持续跑30min后恢复30 min。(2)以75%VO2max跑4 min间歇2 min为一组,连续进行5组后恢复30 min。(3)以100%VO2max跑3 min间歇3 min为一组,连续进行5组后恢复30 min。通过气体代谢法间接测定运动期、恢复期以及整个运动期和恢复期总的底物代谢和能量消耗量。结果:(1)在运动期,以50%VO2max强度运动时,糖氧化量、氧化供能比例、总能量消耗显著低于75%VO2max、100%VO2max强度的运动,脂肪氧化量、氧化供能比例显著高于100%VO2max强度的运动。(2)以50%VO2max及75%VO2max强度运动后的恢复期,糖氧化量、氧化供能比例显著高于100%VO2max强度的运动,脂肪氧化量、氧化供能比例总能量消耗显著低于100%VO2max强度的运动。(3)以50%VO2max及75%VO2max强度运动的运动期和恢复期整个过程中,糖氧化总量、总能量消耗明显低于100%VO2max强度的运动,而以50%VO2max强度运动的运动期和恢复期脂肪氧化总量显著高于100%VO2max强度的运动。结论:(1)在平均耗氧量相同情况下,运动期,持续性运动的脂肪代谢水平高于间歇运动,糖代谢水平、总能量消耗低于间歇运动;恢复期,持续性运动脂肪代谢水平总能量消耗低于间歇运动,糖代谢水平高于间歇运动。(2)在相同运动强度下,运动中以及运动后,肥胖组单位公斤体重的糖、脂肪代谢和能量消耗均低于正常体重组。建议:基于运动过程中能量消耗和底物代谢的特征,从能量消耗的角度,建议肥胖体重者在运动减肥时优先选择中等强度持续运动。由于高强度间隙运动在运动后脂肪的氧化量和供能比例较高,且随着运动强度增加变大,肥胖体重者可以把高强度间隙运动作为补充,发挥运动后过量氧耗的作用。
[Abstract]:Objective: To study the different weight groups in the average consumption of the same oxygen under two different exercise methods in substrate metabolism and energy consumption characteristics. Methods: substrate metabolism and energy using experimental method to obtain the obesity group and normal weight group in continuous motion and intermittent movement in the process of consumption characteristics. The subjects were three exercise test: (1) to exercise intensity 50%VO2max continuous running 30min recovery after 30 min. (2 75%VO2max) to run 4 min 2 min interval for a group of 30 consecutive min. recovery of 5 groups (3) with 100%VO2max 3 min 3 min batch run for a group of 30 consecutive min. recovery of 5 groups by gas metabolism method for indirect determination of movement period, recovery period and the recovery period and substrate metabolism and the total energy consumption. Results: (1) in the exercise period, the 50%VO2max intensity exercise, glucose oxidation, oxidation and energy ratio, the total energy consumption was significantly lower than that of 75%VO2max, 100%VO2 Max intensity exercise, fat oxidation, oxidation and energy ratio was significantly higher than that of the 100%VO2max intensity movement. (2) to 50%VO2max and 75%VO2max after exercise recovery period, glucose oxidation, oxidation and energy ratio was significantly higher than that of the 100%VO2max intensity exercise, fat oxidation, oxidation and energy consumption of the proportion of total energy intensity was significantly lower than that of 100%VO2max the movement. (3) to 50%VO2max and 75%VO2max exercise intensity exercise and recovery period in the whole process, the total oxidation of sugar, total energy consumption was significantly lower than that of 100%VO2max intensity exercise, and to exercise 50%VO2max intensity exercise and recovery period total fat oxidation was significantly higher than that of 100%VO2max intensity exercise. Conclusion: (1) in average under the same oxygen consumption, exercise, fat metabolism level of persistent movement is higher than that of intermittent movement, sugar metabolism, the total energy consumption is lower than the intermittent exercise; recovery period, persistent movement of fat The total energy metabolism level of consumption is lower than the intermittent movement, glucose metabolism is higher than the level of intermittent movement. (2) in the same exercise intensity, exercise and after exercise, obese group unit kg of sugar, fat metabolism and energy consumption were lower than the normal weight group. Suggestions: characteristics of the moving process based on energy and substrate metabolism and from the perspective of energy consumption, body weight in obese recommended exercise to lose weight when the first choice of moderate intensity continuous exercise. Due to oxidation and high strength of clearance of fat in the post exercise for a higher proportion, and with the increase of exercise intensity increases, obesity can bring high strength clearance as a supplement, play after exercise the excess oxygen consumption.
